Brief answer..Why do you want to take lasix?Detailed answer....Hello,Thanks for the query.I have read your query but couldn't understand why do you want to take lasix?Unnecessary consumption of lasix may bring your blood pressure down and may cause loss of sodium and potassium.Too much consumption of salts is not a good thing and should be avoided.For rash,you can take ATARAX.please revert back to me,in case you have something to ask.Best of luckThanks
